But maybe I can help someone who does have a vague idea, to put this infernal quote to rest
Ok She's down there.
So, the quote is probably about:
Lois/ Batgirl or Catwoman (maybe Lana.)
Could be Red Claw/ Poison Ivy/ Harley
I don't remember Supergirl ever being "down" anywhere. And Talia's not important enough to be referred to in a quote.
I'll take a guess..
The security guard, referring to Harley in "Harley's Holiday?"
